4. 1 st Law: Law of Inertia A body at rest will remain at rest And A body in motion will remain in motion Unless…

5. 1 st Law: Law of Inertia A body at rest will remain at rest And A body in motion will remain in motion Unless… Acted upon by an outside force

6. 1 st Law: Law of Inertia Keep on keeping on Truck and Ladder Example

8. 2 nd Law: Law of Acceleration An object in motion, when acted upon by an external force will... accelerate. Remember: acceleration is change in speed If a ball is rolling along the ground and you kick it...

9. 2 nd Law: Law of Acceleration

11. 3 rd Law: Law of Reaction For every action, There is an equal but opposite reaction.

12. 3 rd Law: Law of Reaction Forces always Come in pairs Equal in size Opposite in direction Acting on 2 different bodies

13. 3 rd Law: Law of Reaction
